QUESTION
I have a database with a decently large amount of tick data of all 229 stocks in the S&P/TSX Composite Index. For reference, a single day's worth of data is about 13 million rows.
here's a snippet of data:

Answered 2021-Jun-11 at 20:06I wish you gave some sample data to test with. Would you try a query like this:
QUESTION
I have a table like this with 8 rows
...ANSWER
Answered 2021-May-21 at 18:06You don't mention if multiple a's with the same id are possible or what to do in that case. I'm going to assume you want all a rows included. To do that, you just need to exclude b rows when there is a corresponding a row:
QUESTION
It's not clear to me how to run the Simple Example from the Open Policy Agent Playground from the CLI.
play.rego
...ANSWER
Answered 2021-May-12 at 08:10That's a great question! Unless "evaluate selection" is selected, the Rego Playground always evaluates the entire policy, i.e. all rules included. When you query a policy using opa eval you can either choose to do the same, or as you do in your example - query just a single rule for its value.
If you change the query from "data.play.hello" to just "data.play" it will evaluate the full policy just like the playground:
QUESTION
I am new at OPA/Rego and I am trying to write a policy to check if an Azure Network Security Group contains all the rules that I define on an array
...ANSWER
Answered 2021-May-06 at 18:11Sure! Use a list comprehension and call the function inside of it, then compare the size of the result to what you had before. Given your example, you would replace existRule(rules[i]) with something like this:
QUESTION
In Open Policy Agent (https://www.openpolicyagent.org/)
regarding to Kubernetes, depending which engine is used:
- Gatekeeper: https://github.com/open-policy-agent/gatekeeper
OR
- Plain OPA with kube-mgmt: https://www.openpolicyagent.org/docs/latest/kubernetes-introduction/#how-does-it-work-with-plain-opa-and-kube-mgmt
There are different ways to define validation rules:
In Gatekeeper the
violationis used. See sample rules here: https://github.com/open-policy-agent/gatekeeper-library/tree/master/library/generalIn plain OPA samples, the
denyrule, see sample here: https://www.openpolicyagent.org/docs/latest/kubernetes-introduction/#how-does-it-work-with-plain-opa-and-kube-mgmt
It seems to be the OPA constraint framework defines it as violation:
https://github.com/open-policy-agent/frameworks/tree/master/constraint#rule-schema
So what is the exact "story" behind this, why it is not consistent between the different engines?
Notes:
This doc reflects on this: https://www.openshift.com/blog/better-kubernetes-security-with-open-policy-agent-opa-part-2
Here is mentioned how to support interoperability in the script: https://github.com/open-policy-agent/gatekeeper/issues/1168#issuecomment-794759747
https://github.com/open-policy-agent/gatekeeper/issues/168 In this issue is the migration mentioned, is just because of "dry run" support?.
ANSWER
Answered 2021-May-04 at 20:15Plain OPA has no opinion on how you choose to name your rules. Using deny is just a convention in the tutorial. The real Kubernetes admission review response is going to look something like this:

QUESTION
I'm working on the CNN with one-dimensional signal. It works totally fine with CPU device. However, when I training model in GPU, CUDA error occurred. I set os.environ['CUDA_LAUNCH_BLOCKING'] = "1" command after I got RuntimeError: CUDA error: CUBLAS_STATUS_ALLOC_FAILED when calling cublasCreate(handle). With doing this, a cublasSgemm error occurred instead of cublasCreate error.
Though the nvidia document doubt the hardware problem, I can training other CNN with images without any error. Below is my code for the data loading and set data in training model.
ANSWER
Answered 2021-Mar-29 at 08:12With searched with the partial keywords, I finally got the similar situation. Because of the stability, I used the CUDA 10.2 version. The reference asked to upgrade CUDA toolkit to higher - 11.2 in my case - and problem solved! I've deal with other training processes but this one only caused error. As the CUDA error occurred with various reasons, changes the version could be counted for solution.
